Abstract
The utility model discloses a light-emitting diode (LED) ceiling lamp. The LED ceiling lamp comprises a lamp seat, a lamp panel, a radiator, a plurality of lamp sources and a lens, wherein the radiator is fixed at the rear end of the lamp seat, the lamp panel is embedded at the front end of the lamp seat and is provided with a plurality of round lamp grooves, the lamp sources are embedded in the lamp grooves, the lens is fixed above the lamp grooves, the lamp sources are LED lamps, and the radiator is a compound three-plate radiator. According to the LED ceiling lamp, the LED lamps are used as the lamp sources, the light-emitting angle of the ceiling lamp can be adjusted within the range of 60 degrees to 120 degrees, and luminous efficiency is larger than 90 lumens per watt. By means of the compound three-plate radiator, heat dissipation area is increased, the heat dissipation effect is good, the junction temperature is lowered, and the luminous efficiency is improved. The lamp sources are free of radiation, such as ultraviolet rays and infrared rays. Besides, mercury and other pollutants are prevented from overflowing from a broken fluorescent lamp, and waste ceiling lamps can be recycled. The LED ceiling lamp is beautiful in appearance.
Description
Technical field
The utility model relates to the lamp field, particularly a kind of LED Ceiling light.
Background technology
The LED lamp is a kind of as lighting source, in the market, and heavy construction, indoor and outdoor lighting is used extensivelyr, has had larger improvement in manufacture craft, but because the restriction of lamp manufacturing process and material, the colour rendering index of LED lamp is not high, and the life-span is shorter.Can not give full play to the advantage of LED lamp, affect LED lamp promoting the use of on Ceiling light.
There is the problem of heat radiation and luminous intensity distribution difficulty in existing Ceiling light design: existing heat dissipation technology is the aluminium base heat radiation of limited area, high-power LED chip package on the copper base of very little (about 5mm), make the lamp holder of 1 1W or 3W, then with lantern (tens of---up to a hundred) 1W(3W) lamp holder be fixed on the aluminium sheet with screw or heat-conducting glue and dispel the heat, want heat cloudy owing to deposit between lamp holder and the aluminium base, the area of dissipation of aluminium base is limited, cause the LED work calories to derive, so that the led chip temperature sharply rises, the temperature of aluminium base (being the operating ambient temperature of chip) has substantially exceeded the permission operating temperature of chip, the light decay aggravation that works long hours like this and just cause the LED lamp, brightness reduces, and has shortened service life greatly.
Summary of the invention
In order to overcome defects, the utility model provides a kind of lighting effect good, good heat dissipation and embedded LED Ceiling light attractive in appearance.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of LED Ceiling light, comprise lamp socket, lamp plate, radiator, some lamps source and lens, wherein radiator is fixed on the lamp socket rear end, lamp plate is embedded at the lamp socket front end, lamp plate is provided with several circular light troughs, and the lamp source is embedded in the light trough, and lens are fixed in the light trough top, described lamp source is the LED lamp, and described radiator is compound three-chip type radiator.
As further improvement of the utility model, described radiator is fixed on the lamp socket rear end by screw thread.
The beneficial effects of the utility model are: the utility model adopts LED as the lamp source, and the light fixture beam angle is adjustable in 60-120 ° of scope, and light efficiency is greater than 90lm/W, adopt compound three-chip type radiator, increased area of dissipation, good heat dissipation effect, reduce junction temperature, improved light efficiency; Light source is without radiation such as ultraviolet ray, infrared rays, and the polluters such as mercury that can avoid fluorescent tube to break and overflow, the recyclable recycling of waste and old lamp; Profile is graceful.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Fig. 1 has shown a kind of embodiment of a kind of LED Ceiling light of the utility model, comprise lamp socket 1, lamp plate 2, radiator 3, some lamps source 4 and lens 5, wherein radiator 3 is fixed on lamp socket 1 rear end, lamp plate 2 is embedded at lamp socket 1 front end, lamp plate 2 is provided with several circular light troughs, lamp source 4 is embedded in the light trough, lens 5 are fixed in the light trough top, described lamp source 4 is the LED lamp, described radiator 3 is compound three-chip type radiator 3, and described radiator 3 is fixed on lamp socket 1 rear end by screw thread, and the LED lamp is installed in independently on the lamp plate, increased the luminous volume of light source, profile is graceful; Adopt compound three-chip type radiator, increased area of dissipation, good heat dissipation effect has reduced junction temperature, has improved light efficiency.
