Description

A kind of LED bulb

[utility model field]

The utility model relates to a kind of LED bulb.

[background technology]

LED (light emitting diode) along with the revolution of material technology, will become the substitute products of tungsten filament lamp for general service as the high new light energy source of low-power consumption transform light energy rate at present.Being limited to is that single power of present LED light emitting source is all less, so actual the use all is to utilize many LED light emitting sources to use as the bigger morse signal light of volume, can't be applied in fields such as the less family expenses bulb of volume, decorating lamp bulbs.

[utility model content]

For solving the deficiencies in the prior art, provide a kind of volume less bulb, the utility model by the following technical solutions:

A kind of LED bulb comprises lamp holder, lamp socket, is built in the LED in the lamp socket, it is characterized in that being fixed with collector lens before the LED.LED light can be converged by collector lens, thus the needs of realization illumination.

Above-mentioned LED bulb is characterized in that described collector lens inboard is light collecting part, and the outside is a diffused light portion.The effect of optically focused, reflection and diffusion light was played at optically focused convex lens 41, speculum 42, diffusion light microscopic 43 several positions respectively before and after collector lens was divided into, and made illuminating effect better.

Above-mentioned LED bulb is characterized in that the light collecting part outside of described collector lens is sphere, is provided with groove with the LED matching part, and the LED luminous component is installed in the groove.The LED luminous component is installed in the groove, and LED light can maximum possible be utilized by collector lens, thereby improves luminous flux.

Above-mentioned LED bulb is characterized in that described diffused light portion can be one of concave surface, convex surface, planar structure.Three kinds of different diffused light portion structures can play the needs that throw light in different occasions.

Above-mentioned LED bulb is characterized in that being provided with heat sink outside LED.

Above-mentioned LED bulb is characterized in that described heat sink can be one of following three kinds of structures:

(a) be installed in the LED back;

(b) extend to light direction;

(c) oppositely extend to light direction.

According to the degree of heat of different LED, select different cooling plate structures, can play the purpose of saving cost.Certainly the LED of low heating can be without heat sink, and perhaps adopting lamp socket also is feasible as heat sink directly.

Above-mentioned LED bulb is characterized in that being provided with at the bright dipping oral area shrouding of fixed lens and lamp socket, offers the perforate that blocks mutually with lens on the shrouding.Shrouding is used for fixing lens and lamp socket.

Above-mentioned LED bulb is characterized in that described lamp socket is provided with air-vent.Air-vent is can play good thermolysis for the LED of heat occurred frequently with heat sink, prolongs the service life of LED bulb.

Above-mentioned LED bulb is characterized in that extending bracing frame to light direction in the described lamp socket, and LED is fixed on the heat sink, and heat sink is fastened on the bracing frame, and collector lens bears down on one on bracing frame by shrouding, and shrouding is fixedlyed connected with lamp socket.This is a kind of structure of each position part of more convenient connection.

The light source that directly LED is produced by collector lens is used for illumination, can play and make full use of luminous energy, reach best illuminating effect, and can only adopt single LED to realize the bulb of small size, and can accomplish consistent in shape with existing bulb profile size, make the cost of promoting the use of of LED bulb reduce, can directly the LED bulb be installed on the existing lamp socket, finally utilize the high efficiency opto-electronic conversion performance of LED to play energy-conservation effect.

The single led multi-group light-emitting source that is built-in with that the LED manufacturer that has now produces, thereby improved single led lighting power, the LED that its volume of the LED of this multiple sets of light sources is more singly organized light source wants big, so when making lens, its size also should be made corresponding modification.

The lighting circuit device 2 of driving LED light emitting source can be built in the lamp socket, also can make external parts and be connected on the illuminating line; So the concrete installation site of the lighting circuit device of LED light emitting source can be in the lamp socket in the utility model, also can not be installed in the lamp socket.

The profile of bulb should be identical with existing standard, just need not change the socket of existing illuminating lamp like this when promoting, so can make existing forms such as screw socket or bayonet socket.

[specific embodiment]

Embodiment 1:

With reference to accompanying drawing: a kind of LED bulb, comprise lamp holder 1, lamp socket 5, be built in the LED7 in the lamp socket, be fixed with collector lens before the LED; The collector lens inboard is a light collecting part, and light collecting part is provided with groove, and the LED luminous component is installed in the groove; The collector lens outside is a diffused light portion, is interior concave spherical surface.Be fixed with heat sink 6 outside LED, heat sink is bowl-type to the light direction extension.Be provided with the shrouding 3 of fixed lens and lamp socket at the light-emitting window position of lamp socket, offer the perforate that blocks mutually with lens on the shrouding; Lamp socket is provided with air-vent 10.

The lighting circuit device 2 of driving LED light emitting source is installed in the bulb in the present embodiment, is connected with the external power line by lead 8.

Embodiment 2:

With reference to accompanying drawing, extend bracing frame to light direction in the lamp socket in the present embodiment, LED is fixed on the heat sink, and heat sink is fastened on the bracing frame, and collector lens bears down on one on bracing frame by shrouding, and shrouding is fixedlyed connected with lamp socket.The collector lens inboard is provided with groove, and the LED luminous component is installed in the groove.
