Abstract
The utility model discloses a kind of LED flat lamps, it includes aluminium frame, the inner ring surrounding of aluminium frame is provided with receiving cavity, it accommodates and light source board is installed on the bottom of chamber of cavity, light source board is connected with external non-isolated driving power, it accommodates and is arranged with the diffuser plate, light guide plate and reflecting paper stacked successively on the accent of cavity, the side wall of the LED particle face light guide plate of light source board, the light that the LED particle of light source board is sent out is imported from the side wall of light guide plate, and modeling alclad holder or the plastic holder of aluminium are provided between the wiring board of light source board and the bottom of chamber for accommodating cavity;Advantage is significantly to be kept apart the wiring board of the light source board i.e. electric part of light source board and aluminium frame by setting modeling alclad holder or the plastic holder of aluminium, to effectively increase the creepage distance between light source board and aluminium frame, even if thus electric shock risk can be avoided well if LED flat lamp failure.
Description
Technical field
The utility model is related to a kind of LED lamps, more particularly, to a kind of LED flat lamp.
Background technology
At this stage, two kinds of drive schemes of LED flat lamp generally use, majority use isolation drive scheme, and minority is using non-
Isolation drive scheme.Two kinds of drive schemes respectively have advantage and disadvantage:The advantages of isolation drive scheme is that safety was easy, without considering to climb
The good heat dissipation effect of electrical distance, light source board, disadvantage are that the price of driving is somewhat expensive, the volume of driving is larger;Non-isolated driving side
The advantages of case for driving price it is relatively cheap, driving small volume, the price of driving shell it is also relatively cheap, disadvantage is safety
It is difficult solution, creepage distance is inadequate, the heat dissipation effect of light source board is bad.
It is non-when considering that natural selection uses non-isolated drive scheme when cost in the industry, but using non-isolated drive scheme
The output coupling part of isolation drive power supply i.e. light source board are still high-pressure section, and LED flat lamp once fails, then can be because climbing
Electrical distance not enough generates electric shock risk, it is therefore desirable to solve the problems, such as that creepage distance is inadequate.
Invention content
The technical problem to be solved by the utility model is to provide a kind of LED flat lamps, use non-isolated driving power,
And it disclosure satisfy that creepage distance.
Technical solution is used by the utility model solves above-mentioned technical problem:A kind of LED flat lamp, including aluminium frame,
The inner ring surrounding of the aluminium frame is provided with receiving cavity, and light source board is equipped on the bottom of chamber of the receiving cavity, described
Light source board is connected with external non-isolated driving power, and the diffusion stacked successively is arranged on the accent of the receiving cavity
Plate, light guide plate and reflecting paper, the side wall of the light guide plate described in the LED particle face of the light source board, the light source board
The light that LED particle is sent out is imported from the side wall of the light guide plate, it is characterised in that:The wiring board of the light source board with it is described
Receiving cavity bottom of chamber between be provided with the modeling alclad holder or plastic holder of aluminium.
The wiring board of the light source board passes through bond plies and the modeling alclad holder or the plastic branch of the aluminium
The medial surface of frame is bonded, the lateral surface of the modeling alclad holder or the plastic holder of the aluminium by bond plies with it is described
Receiving cavity bottom of chamber fitting.Since the plastic holder of modeling alclad holder or aluminium of setting is insulator, heat conductivility is less than
Aluminium frame, therefore the heat dissipation problem of light source board can be well solved by bond plies.
Compared with prior art, the utility model has the advantage of:Alclad holder is moulded by setting or the plastic holder of aluminium will
The electric part of wiring board, that is, light source board of light source board is significantly kept apart with aluminium frame, to effectively increase light source board and aluminium
Creepage distance between frame, thus even if LED flat lamp can avoid electric shock risk well if failure.
Description of the drawings
Fig. 1 is the overall structure diagram of the LED flat lamp of the utility model;
Fig. 2 is the side view of the LED flat lamp of the utility model;
Fig. 3 is the partial structural diagram after the LED flat lamp of the utility model is decomposed.
Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing embodiment.
The utility model proposes a kind of LED flat lamp, as shown in the figure comprising the inner ring surrounding of aluminium frame 1, aluminium frame 1 is set
It is equipped with and accommodates cavity 11, accommodate and light source board 2 is installed on the bottom of chamber of cavity 11, light source board 2 is connected with external non-isolated driving
Power supply 3 accommodates and is arranged with the diffuser plate 4, light guide plate 5 and reflecting paper 6 stacked successively, the LED of light source board 2 on the accent of cavity 11
The side wall of 21 face light guide plate 5 of particle, the light that the LED particle 21 of light source board 2 is sent out are imported from the side wall of light guide plate 5, light source board 2
Wiring board 22 and the bottom of chamber for accommodating cavity 11 between be provided with modeling alclad holder 7, alclad holder 7 is moulded by light source board by setting
2 wiring board 22 is that the electric part of light source board 2 is significantly kept apart with aluminium frame 1, to effectively increase light source board 2 and aluminium
Creepage distance between frame 1, thus even if LED flat lamp can avoid electric shock risk well if failure.
In the present embodiment, the inside face paste that the wiring board 22 of light source board 2 passes through bond plies 8 and modeling alclad holder 7
It closes, the lateral surface of modeling alclad holder 7 is bonded by bond plies 8 with the bottom of chamber for accommodating cavity 11.Due to the modeling alclad of setting
Holder 7 is insulator, and heat conductivility is less than aluminium frame 1, therefore can well solve light source board 2 by bond plies 8
Heat dissipation problem.
In specific design, also modeling alclad holder 7 can be replaced with the plastic holder of aluminium.
In the present embodiment, non-isolated driving power 3 uses the prior art;Diffuser plate 4 and light guide plate 5 are all made of existing skill
Art;Existing three-in-one reflecting paper can be used in reflecting paper 6;Modeling alclad holder 7 can be used existing modeling alclad material and be made, aluminium packet
Modeling holder can be used existing aluminium covered material and be made, and modeling alclad holder 7 or the plastic holder of aluminium can be made into U-type groove structure.
